Firm Profile:

Established in 1995 by Joanne McCallum and Greg Sather, McCallum Sather Architects (MSA) is an award winning architectural firm with a special focus on integrating sustainable design principals into our design process. We provide quality architecture, interior, and project management services through an interdisciplinary perspective and integrated design approach.

Our breadth of experience includes both renovation and new construction, with projects ranging in size from small community initiatives to large, multi-million dollar new construction projects. Although we complete projects for a variety of clients, the bulk of our experience has been for healthcare, institutional, municipal and post-secondary projects.

Our in-house staff is comprised of Architects, Registered Interior Designers, Technologists and, most recently, a Mechanical Engineering division, MSE. Our multi-disciplinary team was developed to provide highly coordinated construction documents and design to our clients as well as provide enhanced LEED Facilitation. We can act as a “one stop shop” for many projects. For more information please visit our website at
